TO THOSE WHO SAID IT COULDN'T BE DONE! installing an aftermarket hu is simple! DIY?
I have a 2003 E55 AMG. I installed a AVIC Z1 and it was SIMPLE! From factory I had that karman logic unit installed. The infamous "10" speaker system
riiightt. They are counting tweeters, etc. This may be good to turn into a sticky since nobody and I mean nobody understands this fiber optic stuff.
The solid red wire with a yellow stripe from your factory wiring harness goes to your CONSTANT 12V connection.
The solid brown wire from your factory wiring harness goes to your GROUND WIRE.
The solid red white stripe wire (found at the cigarette lighter, do a search for hot wiring the valentine and you'll find it) goes to your 12V SWITCH WIRE.
Your illumination wire goes to one of your tailights HOT wire. Don't remember the color but can get that for you.
OH and the infamous speakers =) The headunit is fiber opitcally run to the factory amp which sits on the left hand side of the trunk. Should be easy to find underneath the carpet or whatever its called. From here WIRES WIRES WIRES go to speakers. There will be a set of 5 wires! 4 of them go the front left/right, etc. Then one set goes to your center speaker upfront.
CLIP these wires and then attach your own wires to these and run them to your headunit. Most high end head units have an good enough amp to power up these speakers. BELIEVE ME. The problem with setting up new speakers is that they are a special size I think 6 5/4 or something instead of 6 1/4. Either way clip these wires and do this:
RIGHT REAR WIRES ARE = +white -brown with white stripe
RIGHT FRONT WIRES ARE = +black -brown with black stripe
LEFT FRONT = + solid gree - brown with green stripe
LEFT REAR = + pink - brown with pink stripe
FYI
+ = positive and - = negative
NOTE: use a 16 or 18 guage wire to attach to these factory wires when running back.
You must attach wires and make sure you label them correctly and such and wire them through the car to the back of the head unit.
IMPORTANT:
Depending on the head unit you have the ohm calculations you MAY OR MAY NOT be able to connect the center speaker. I was unable to unless I wanted to add a two channel amp and bridge it. This is a little more tricky and for the added little extra sound you got not worth it at all.
From there all of your other components such as the bluetooth, XM navtraffic and other utilites only run off ur 12V POWER SWITCH or 12V POWER CONSTANT and a GROUND WIRE. I have mentioned were those can be located already.
Guys is this simple or what? =) This is for all you young owners out there that want to install an aftermarket head unit. I will have pics up if there is interest at the end of the weak. I'm currently fabricating a nice custom bracket that will have AMG below the headunit glowing in a light blue like the AMG side sills
The only thing I have yet to find is the infamous VSS wire... hehehe it has alluded me thus far and I know it exists. The can bus junk you don't have to use. I'll let you know when I have discovered this mysterious wire. The nav unit will work without it no problem and everything else is honestly self explanatory on the install. I have outlined the most difficult and intimidating part for most people installing head unit in these fiber optic cars.
I love my E55 even more now... muah! sorry guys i'm just excited.. back to studying for my board exam in february peace
Leave a message on here if have anymore questions. I'll check it over the next few days or if you have any news on how to find that VSS wire. thanks.

There was never really any problem installing an aftermarket head unit. You simply do an amp by-pass like you did. The problem is that you cannot use your steering wheel controls. That has not been figured out.
Ted
not to mention I never found anything on search. Either way who needs those pesky steering wheel controls
I honestly only use them to manipulate the MPH or range settings, etc.
I'm studying for the USMLE =) AKA boards for the MD
sooo anybody know where this VSS wire is at all?
oh jangy I changed the title of my post just for you... lmao

From an integration perspective I think its more or less a step backwards. Just because it is different and has a few nice things doesnt make it better to the overall Mercedes philosophy.
When was the last time I touched the dials on the front face .... long before I bought a Mercedes.

I will give you guys pics when I am back in home.
Ted you have a pm




For anyone who is interested in resale value there is no point in discussing aftermarket units and cutting wires. The market is slowly going MOST optical and what will happen after a few years is that some of the larger players will enter with some reasonable products.
To me, many of these products appear extremely primitive and backward. Someone asked me once to install the best sound system that money can buy into their car. What they thought was the best was about 10% as much as what it actually costs.
